QuestionQUESTION: Hello,
I have an older (2000/2001) Noma (Murray) snowblower which I got used.
The Model number is 633124x8
Serial is S001136760820
I finally got the engine running correctly, fixed the governor linkage, reset
the valve clearance, and the air gap, rebuilt the carb, changed belts and feel
pretty handy with fixing things on it.
The machine is in good shape, but the previous owner might not really
known how to care for it.
My question is this. Today after throwing snow for about 30 minutes, my
forward gears went away. I am able to go in reverse, but unable to move
forward.
I took the bottom panel off and the rubber disc is making contact with the
metal disc. I tried adjusting the length of the cable which controls the
engagement of the friction wheel, and perhaps now it engages "more"...? If I
put the machine in gear and attempt to move forward the wheels spin if they
are off the ground, and if I try and stop them, they put up a good fight, I
don't hear anything slipping, or a chain jumping off teeth. Yet, as soon as I
put the machine down, it does not move under its own power.
I can peak in the hole on the back panel and see that the rubber disc is
spinning, so it and the metal disc are making contact, but still no forward
movement.
The drive chain does look like it has a bit of slack in it, but has NOT slipped
off the teeth, and as I said before, it does go backwards under its own power.
I have ordered a new rubber disc, but I don't really think this is the issue.
Any ideas?
Thanks
Daniel

I Used the 200 Model for Reference.
>>Check the Hex Shaft (#210 in the Breakdown) that the Drive Disc is Attached to. If this Shaft Rounds the Edges Off, you will have the Problem you Described.
>>The Rubber Disc can be the Cause, but it is Always Better to be Safe and Check the Hex Shaft.
>>Does the All Steel Disc have Grooves that have Worn in it from the Rubber Disc?
>>This is a Simple Drive and Usually the Drive Disc, Driven Disc, Hex Shaft or Spring are Usually the Cause of this Problem.

QUESTION: Hi John,
I went to the site you mentioned, however #210 in the diagram is the disc
assembly, not the hex shaft as you had suggested. Did you mean to say part
#215? That does say SHAFT, HEX TRACTION.
Thanks for your help.
Daniel

>>My Mistake. It is #215, the Shaft, Hex Traction that I was Referencing to.
